The theory of "yang transforming qi and yin shaping up body" comes from Huangdi Neijing (Inner Canon of Yellow Emperor),which describes the basic form of human metabolism dominated by "yang transforming qi":the effect of " yang transforming qi" leads the energy metabolism of human body,while the effect of "yin shaping up body" leads the material metabolism. Metabolic syndrome is a clinical syndrome with metabolic disorders of protein,fat and carbohydrate. The theory of "yang transforming qi and yin shaping up body" has a strong guiding value for the pathogenesis analysis and clinical differentiation and treatment of metabolic syndrome. Yin and yang represent the two basic trends of the change and development of things,and the functions of "transforming qi" and "shaping up body" are the main manifestations of them in metabolism. From this perspective,this paper suggests that the key pathogenesis of metabolic syndrome should be "insufficiency of yang transforming qi and impairment of yin shaping up body" based on the mutual assistance of yin and yang. On this basis we take "coordinating yin-yang and promoting the reproduction of them" as the main directions of therapy,which provides a new idea for the treatment of metabolic syndrome.

The treatment of inner ear disease is developing towards local drug delivery to avoid drawbacks of systemic approach.The cochlear implants with drug delivery functions,a newly developed method of drug delivery into inner ear for treatment,has become the focus of research in recent years.In this review,we will describe recent advances in characteristics,product developments and applications of different types of drug loaded cochlear implants for local therapy.

Objective To study the effects of the intelligent hearing-assistive system incorporated in Nuro-tron cochlear implants(CI),including the autonomic acoustic scene recognition(ASR),intelligent strategy config-uration as well as the objective and subjective hearing improvements on recipients.Methods ① To evaluate the per-formance of the ASR matule,in a sound-proof room,the preset five kinds of test audios,including speech,noise,speech in noise,pure music(without human voice)and non-pure Music(with human voice)were played.Each type of scenes included 6 to 9 5 min test files.The prediction accuracy and scene switching times were calculated.② In order to evaluate the noise-reduction performance of the ABeam technology in the speech enhancement module,13 Nurotron? CI recipients were recruited and their speech recognition rate when ABeam was"ON"and"OFF"with noise coming from 90°,180°or 270°were tested,individually.Also,their subjective hearing feedback was evaluated through visual analogue scale(VAS)evaluation.Results The ASR module achieved high prediction performance,with prediction accuracy 99%±4%,96%±9%,94%±12%,94%±15%,92%±13%for speech,noise,noisy speech,pure music and non-pure music,respectively.The scene transation times for each individual scene were 1.1 ±0.3,1.4±0.7,1.3±0.5,1.4±0.8 and 1.3±0.5,indicating that the prediction was also stable.When noise came from the sides and behind of recipients and speech signal from the front,the adaptive dual microphone noise re-duction algorithm ABeam significantly increased the speech recognition score(SRS)in 5 dB signal-to-noise(SNR)environment(P<0.001),with an average increase of 15.92%.Especially when the noise came from 180 degree backward,the SRS increased 28.68%when ABeam was"0N",which was significantly higher than when ABeam was"OFF"(P<0.01).Conclusion The intelligent hearing-assistive system can help CI recipients automatically configure appropriate SPSs under different environments,improving the speech intelligibility and hearing comfort.
